Answer 1

//load the XML in memory from a document or other ways

XDocument doc = XDocument.Load("");
var values = doc.Descendants("settingB");
foreach( var value in values )
  {
     Console.WriteLine( value.Value );
  }
Console.ReadLine();

Answer 2

I am also isn't professional, but I think something like this should works.

XmlDocument xml = new XmlDocument();
xml.Load("");// load from file for example
foreach(XmlNode node in xml.DocumentElement["settingB"].ChildNodes){
    Console.WriteLine(node.Attributes["val"].Value);
}
Console.ReadLine();
